
FLASH / STROBE
Various configurations of cables are needed to match the requirements of various CFV-50c / Hasselblad body combinations.
In addition, some modification might be required for certain camera bodies. Neither of these points however are directly
related to CFV-50c use but rather to general flash use. See the chart on the following page for details.
503CWD or 503CW+CFV-50c combination
A 503CWD or 503CW+CFV-50c combination offers TTL flash control with some slight adjustments. As the reflective charac-
teristics of the digital sensor are different to film surface characteristics (for which the TTL function was originally designed),
this function has to be slightly ‘tricked’ to perform correctly. Proceed as follows:
Move the film speed selector on the camera so that is becomes approximately 1⁄ f/stop higher than the ISO setting on the
CFV-50c. Therefore, for example, when the CFV-50c is set at 100 ISO, the ‘film speed setting’ on the camera should read 160
ISO, and so on. Testing for the most suitable compensation that suits you is recommended.

STUDIO FLASH/STROBE UNITS WHEN TETHERED TO A DESKTOP COMPUTER
If the CFV-50c is tethered to a computer that is connected to a regular electricity supply system as well as a studio flash/
strobe unit that is also connected to a regular electricity supply system/generator system, then make the following connec-
tions instead. For your own safety and to protect the electronics in the CFV-50c, please ensure you do this correctly.
a) Connect the flash input sync cable from the sync contact (PC connector) on the lens to the flash sync IN terminal on the
CFV-50c.
b) Connect the flash output sync cable from the flash sync OUT terminal on the CFV-50c to a regular flash/strobe sync
cable that is connected to the unit.

CFV50C AND HASSELBLAD 200 SERIES CAMERAS
Connection to 200 series cameras depends on whether they are modified or not (contact your local Hasselblad Service Cen-
ter about modification). TTL is also possible if the flash/strobe unit allows. See the appropriate camera manual for further
details.
Please note the difference below – unmodified cameras can only use C lenses (C/CF/CFi etc) at the C-mode setting whereas
modified cameras can use C and F-type lenses.

CAMERAS WITH PORTABLE FLASH/STROBE UNITS WITH C TYPE LENSES:
a) Connect the flash input sync cable from the sync contact (PC connector) on the lens to the flash sync IN terminal on
the CFV-50c.
b) Connect the flash output sync cable from the flash sync OUT terminal on the CFV-50c to a regular flash sync cable that
is connected to the unit.
c) Use the C-mode setting.
d) Shutter speeds faster than 1/90 sec allowed.

MODIFIED CAMERAS WITH PORTABLE FLASH/STROBE UNITS WITH F AND CF TYPE LENSES:
a) Connect the standard PC /flash / strobe sync cable from the sync contact (PC connector) on the camera body to the unit.
b) Use F type or CF type lenses at the F-mode setting.
c) Use a shutter speed no faster than 1/90 sec.
